T aZZwhom itmay concern."

Be it known that we, VnNoEL J. TIGHO'TA, and Aoeosr TICI-IOTA, citizensof the United States, residing at Dodge, in the county of Dodge, Stateof Nebraska, have invented a new and useful Draft Equalizer, of whichthe following is a specification.

This invention relates to draft equalizers and is more particularlydesigned as an improvement upon the structure disclosed in Patent No.1,196,140 issued to us on May 12, 1914.

One of the objects of the invention is to strengthen the structure,render the mech anism more compact, and insure the proper operation ofthe parts under all conditions.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the conr bination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodimentof the invention herein disclosed, can be made with in thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown. In said drawings Figure 1 is a plan view of the equalizer.Figure 2 is a front elevation thereof. Figure 3 is a section on line 33,Figure 1. Referring to the figures by characters of reference 1designates a clip adapted to be fastened to the tongue or other portionof the structure to-be drawn and is provided with forwardly extendingupper and lower arms 2 the forward ends of which are connected by apivot bolt Son which is fulcrumed the inner end of a short lever 4.Arranged within the tongue 2 and-back of the pivot bolt 3 is anotherpivot bolt 5 to which is connected one end portion of a long lever 6there being wear plates 7 forming one end portion there of and whichengage the bolt 5. The plates are connected by a pivot bolt 8 andpivotally mounted on this bolt and between the plates 1s a lever 9 whichextends transversely through the tongue 2 and between the bolts SerialNo. 476,786.

3 and 5 and is connected by a link 10 to the lever 4::- This link isadapted to receive a bolt 12 extending through the lever 4, there beinga series of apertures 13 for the reception of the bolt, these aperturesbeing provided in the lever 4. That portion of the lever 9 between thebolts 3 and 5 is curved parts breaking is practically eliminated. As

the bell crank has a limited movement it is possible for the two levers4 and 6 to have a limited independent movement, thereby to facilitatestarting of a load The parts can be readily adjusted to vary thedistribution of the load, simply by shifting the position of the link 10relativeto the lever 4.

What is claimed is eluding upper and lower members, a lever therebetweenhaving limited relative movement, a short draft lever pivotallyconnected to the front end of the tongue, a long draft lever pivotallyconnected to an intermediate portion of the tongue, the two levers beingextended in opposite directions, an equal- 7 A draft equalizercomprising a tongue 1nizing lever pivotally mounted within the longdraft lever and extending transversely through the tongue, a linkconnection between said equalizing lever and the short draft lever, alink connection between the equalizing lever and the first named lever.
